Exercise 2 Marble Maze

This is a 3 level 3D game where the player controls a ball using arrow keys(up, down, right and left) or letters (w,a,s,d) through a maze of obstacles. Levels get harder as the player progresses. There are trigger objects throughout the game that if collided with can make the ball bounce back. If the ball falls off the platform, the player is brought back to the starting point of that level. There are unlimited number of retries allowed.  The player must take into consideration their speed and the trigger objects if they want to clear all the levels.
